What is your question?
I have had the tranny service , filter, etc. New Plugs replaced both bank 1 and 2 sensors, mass flow sensor, and it reads I need to replace the sensors? All service has been done for the 120 K maintenance. Where do I go from here, my independent mechanic is stumped as well as I>

Which sensors are being flagged as failing or more importantly what are the specific codes stored in the computer. Sometimes a code say engine running lean which should signify a vacuum leak can really be an air flow meter problem even though code stored is not specifically an air flow failure code. A professional grade scan tool is needed to read live data from various sensors to see if they are actually performing correctly or masking another problem.
